A group of people attempt to bake the largest vegan cake the used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. How many kilograms of cocoa powder and dates do they use?

Answers

Answer: 187 kilogram

Step-by-step explanation:

Let the kilogram of dates be represented by x.

Since they used 17 kilograms of cocoa powder which is about one-tenth the amount of dates. The dates will be:

= 1/10 × x = 17

0.1x = 17

x = 17/0.1

x = 170 kilogram

Date = 170 kilogram.

Cocoa powder = 17 kilogram

The total kilogram of date and cocoa powder used will be:

= 170 + 17

= 187 kilogram

Our world has always been faced with the problem of discrimination. It is one of the most discussed topics nowadays and throughout history. In all countries there is most likely at least one type of discrimination that affects different groups of people. The definition of discrimination is the denial of opportunity or equal rights for a specific group of people that may be differentiated by things such as their religion, color of skin, or gender. Discrimination can be confused with other terms such as prejudice and stereotype. The world we live in has been struggling with this sensitive subject for as long as we have recorded. Stereotypes are images held in our minds in regards to certain racial or cultural groups, without consideration of whether the images held are true or false. Stemming from stereotypes is prejudice. The prejudicial attitude occurs when we prejudge a person, good or bad, on the basis that the stereotypes associated with the person or group being prejudged are true. Discrimination is the combination of the terms mentioned above, but involves actually acting out with unfair treatment, directing the action towards the person or group. Prejudice and discrimination do not just occur racially, but it is found among gender, religion, culture, and geographical background. Remember that prejudice is a result of attitude and discrimination is a result of action.

Many people believe discrimination has made big steps forward, but has it really? If it has, why do people still get turned down, receive hate mail, or get ridiculed simply because they differ from each other. I guess these are questions we must ask ourselves. I guess you could also ask yourself if you have ever called anybody a name, looked at them different or judged them when you did not even know them or understand them. You may be thinking “That is not discrimination,” but, in fact, it is.

Step-by-step explanation:

As we can see in hint through it we can identify that it is right angled triangle so here

AB = 6

FE = BC ( being corresponding sides of congruent triangle)

BC = 8

Now In triangle ABC

perpendicular (p) = 6

base (b) = 8

hypotenuse (h) = ?

By using Pythagoras theorem we get

h = √ p² + b²

= √ 6² + 8²

= √ 100

= 10

So Now

a line that includes the point (5, 1)and has a slope of 1

Answers

point slope form:
y-1 = 1(x-5)
y-1 = x-5

slope intercept form:
y = x-4

standard form:
-x + y = -4

Find the slope of y-intercept of the line represented by the table. Please look at the photo

Answers

Answer:

The slope is m= 4 and the y intercept is b= 9

Step-by-step explanation:

The slope is found by using change in y over change in x, or rise over run. From the table, this means, how much does y change for every time x goes up. As you can see, every time x increases by one, y increases by 4. So that´s your slope. The y intercept is when the line crosses the y axis, where x=0. Because you already know the slope, and that when x is one, y is 13, all you have to do is to know that going backwards by one for x means going backwards by 4 for y, and 13-4 is 9.

Mrs. brown has 8 more boys than girls in her class and has a total of 26 students. Determine how many girls and boys are in the class.

May I please get some help ASAP?

Answers

Answer:

There are 9 girls in the class and 17 boys in the class

Step-by-step explanation:

Set up a system of equations where b is the number of boys and g is the number of girls

b + g = 26

b = g + 8

Solve by substitution by substituting g + 8 as b into the top equation

b + g = 26

(g + 8) + g = 26

2g + 8 = 26

2g = 18

g = 9

So, there are 9 girls in the class. There are 8 more boys than girls, so add 8 to this to find the number of boys:

9 + 8

= 17

So, there are 17 boys.

There are 9 girls in the class and 17 boys in the class.

Answer: 9 girls 17 boys
since he has 8 more boys than girls.
The amount of girls 9
More than 8 so
9+8=17
So 17 plus the 9 girls would be 26 students

A toy manufacturer is going to produce a toy that is a scale model of the giant robot in last summer's super hero movie, where 1 cm = 6 feet. If the robot in the movie was 36 feet tall, what will be the height of the toy?

Answers

Answer:

182.88 cm

Step-by-step explanation:

36/6 is 6 and 182.88 are in 6 feet

5.977cm will be the height of the toy when a toy manufacturer is going to produce a toy that is a scale model of the giant robot in last summer's super hero movie.

when 1 cm = 6 feet. If the robot in the movie was 36 feet tall, then we need to find  the height of the toy.

What is 1 feet = ___cm?

1 feet = 1/6cm=0.1666cm.

From given,

when 1 cm = 6 feet. If the robot in the movie was 36 feet tall, then we need to find  the height of the toy.

then 1 feet = 1/6cm=0.1666cm

As 1 feet is 0.1666 cm , to find for 36 feet we need to multiply 1 feet value with 36.

If it is 36 feet =36*0.1666=5.977cm

Therefore 5.977cm will be the height of the toy.
